ALONZO O. BARNES, JR, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OFONE-HALF HIS RIGHT TO ALQNZO G. BARNES, OF SAME PLACE.

IM PROVEM ENT IN STENCIL-PLATES.

Specification forming part of Letters Patent No. 203,992, dated May 21,1878; application filed February 7, 1878.

To all whom c't may concern:

Be it known that I, ALONZO O. BARNES, J r., of Philadelphia,Pennsylvania, have invented a new and useful Improvement in Stencil-Plate's, of'which the' following is a specification: 1

My invention relates to that class of stencilplates in which part of theplate is made to form the letter or figure by cutting away the metal oneach side of the same at such other points as the character of the saidletter or figure may determine; and the object of my invention is tomake a series of plates of this class, one figure or one letter of thealphabetv being formed on each plate, which is cut away to such anextent, on each side of the figure or letter, that the limit of thecolor which has been imparted to a surface through the openings in oneplate will serve as a guide for the proper adjustment of another, or thesame plate for the production'of another figure or letter at a properdistance from the first.

In the accompanying drawing, Figure 1 is a stencil-plate for the figure5, which is of the same material as the plate, the latter being cut awayon each side of the figure to an extent indicated by the lines a b.

The making of stencil-plates by cutting away the metal on opposite sidesof the figures or letters which constitute part of the plate is old; butmy improved stencil'plates are especially constructed with the view tothe ready and accurate spacing of the letters'or figures produced by theaid of the plates. Thus, Fig. 2 shows the coloring which would beproduced by the aid of the plate, Fig. 1', the opposite edges a b of theopening in the plate defining the limits at and b of the colors in Fig.2. Now, if 2 is to be the adjoining figure, the stencil-plate, Fig. 3,is so adjusted that the edge d of its opening shall coincide, or nearlyso, with the edge b of the color in Fig. 2; and if the color be nowapplied to the second stencil-plate while it is in this position, weshall have the figure 2 on a ground color, which ad'- joins or forms acontinuation of the ground color on which the figure 5 appears, and thetwo figures will be properly spaced.

There should be but one figure or one letter on each plate, for it isthe main aim of my invention to furnish retail dealers and others with aset of plates for all the letters of the alphabet and a set of platesfor all the figures, so that there can be the same interchanging of theletters and of the figures which ordinary type affords, and. so that thetradesman can prepare his own price-cards, &c., with facility, and withthe' proper exactitude as regards spacing.

It will be understood that after the lettering or figuring with myimproved stencilplates is completed the ground colors must be finishedabove and below the figures or letters, as shown in Fig. 4, and this maybe accomplished by the aid of the stencil-plate, Fig. 5, containing anoblong opening.

Fig. 6 shows a letter-plate made according to my invention.

I claim as my invention- A series of stencil-plates for producingletters or figures, each plate having a single letter or figure formingpart of the said plate, and bounded laterally by openings (one on eachside) arranged in respect to the figure or letter, as described, so thatthe color imparted to a surface through the openings of one plate inproducing one letter or figure will serve as a guide foradjusting thesame or another plate for the production of the same or an other letteror figure at aproper distance from the first, all as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
